Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Vascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitor; inhibits VEGFR-1, -2, -3, and PDGFR-β, Kit, and RET.
Technetium Tc-99m mebrofenin is a radiopharmaceutical that, after intravenous administration, is taken up by hepatocytes via organic anion transporting polypeptides (OATPs) and excreted into the bile canaliculi via multidrug resistance-associated protein 2 (MRP2). It allows scintigraphic evaluation of hepatobiliary function by emitting gamma radiation detectable by a gamma camera.
AXUMIN (florbetaben F 18) is a diagnostic radiopharmaceutical for PET imaging of beta-amyloid plaques. The recommended dose is 300 MBq (8.1 mCi) administered as a single intravenous bolus injection over 10-15 seconds, followed by a saline flush.
5 mCi (185 MBq) administered intravenously as a single dose for hepatobiliary imaging.

The terminal elimination half-life is approximately 2.7 hours (range 1.5-5.0 hours) in patients with normal renal function; this supports twice-daily dosing, but may be prolonged in renal impairment.
Terminal elimination half-life is approximately 1.5 hours (range 1-2 hours) in patients with normal hepatic function. In patients with hepatic impairment, half-life may be prolonged up to 4-6 hours.
Renal elimination of unchanged drug accounts for approximately 60% of the administered dose; fecal excretion accounts for approximately 35% (mainly as unchanged drug); biliary excretion contributes to fecal elimination; less than 1% is excreted in urine as metabolites.
Primarily biliary excretion: 85-90% of administered dose is excreted into bile via the hepatobiliary system within 2 hours, with minimal renal elimination (<5%) and fecal excretion accounting for <2%.
